Alpha Males: Tough Guys or Tough Guise? In the animal kingdom the presence of an alpha male is often part of the social order. These dominant males find their rank amongst their peers through displays of physical prowess and dominance. Earning this esteemed position often affords ample opportunity to mate in a system developed to ensure only the strongest and most resilient offspring. In American society today‚ even the considerably less masculine men often find ways to woo a partner. Despite this

The effect of Lead ions on amylase activity Aim What is the effect of Lead ions on the enzyme Amylase. And does it have an inhibitory effect‚ which causes the substrate‚ in this case starch to be blocked from the reaction process in the enzyme catalyst. Also is the effect reversible or irreversible‚ which is put on the amylase. Method Apparatus and substances required Test tube holder 2% starch solution 6 boiling tubes labelled 1 to 6 1% lead nitrate solution 6 test tubes labelled A to E‚

Josh Huggard Mr. Neale SBI3U1 November 6th‚ 2014 Spit and Armpit Lab Partners: Kara Washer and Josh Young Abstract This lab shows the use of salivary amylase with strong and weak starch mixtures to break down complex carbohydrates into simpler sugars. This lab was conducted to physically see the breakdown of carbohydrates into simpler sugars (glucose‚ fructose‚ galactose) using the salivary amylase enzyme. This is extremely important to all metabolic functions in the human digestive system. It

6. DATA ANALYSIS - First‚ the reliability of the questionnaire (both customers and retailers) was checked using IBM SPSS Version 20. Cronbach’s alpha is a measure of internal consistency‚ i.e‚ how closely related a set of items are as a group. It is considered to be a measure of scale reliability. If the value of Cronbach’s α is greater than 0.6‚ one can proceed with further analysis. If the value of α is less than 0.6‚ the questionnaire needs to be redesigned. 6.1 Reliability Testing- • Customer’s

Question How will the addition of different pH buffers to amylase affect the rate of starch digestion measured using starch and iodine? Introduction Amylase is an enzyme found in human saliva and pancreas. It is the digestive enzyme that is needed to breakdown starch molecules. Amylase must be kept at certain conditions to function at its optimum level. This experiment will explore the effect of pH (1‚ 4‚ 7‚ 10‚ and 14) on the function of amylase by using starch and iodine. Usually iodine has a orange-yellow

Charity is one of the leading foundations of America and even the entire world. It brings people together to provide for those in need. Without charity‚ the lives of many would be crushed or some even lost. A charity organization I was apart of‚ called Alpha Charity League (ACL)‚ assembles men from the ages of 12 through 18 to get together and raise money for local charities‚ like the Chris Saiz Foundation. If Blinn could make another chapter of ACL and offered 15 hours of credit for participating‚ not

energy. The goal of this lab was conducted to determine the optimal temperature for bacterial and fungal Amylases and evaluate how temperature affects the catabolic rate of enzymes. Enzyme reaction rate was measured using an Iodine test in which drops of starch solution with either fungal or bacterial Amylase exposed to different temperatures were mixed with Iodine. Iodine is a dark blue color in the presence of starch and turns light yellow in its absence. Bacterial Amylase had an optimal temperature

Lab: investigating hooked law with springs Purpose: to find spring constants of different springs using the slope of a graph of change in heights vs. the weight force. Also‚ to be able to understand how spring constants change when you add springs in a series or paralle Pre lab predictions: We predicted that the graph of gravitational force (mg) as a function of stretch (delta x) would look like Data: Spring #1: y = 8.2941x + 0.0685 This table represents the different distances that
